The 9910 is a continuous feed unit with a high-speed 1925 RPM permanent magnet motor. Like all 9000 series Waste King disposals, it is built with the 3-bolt mount. It includes the power cord, which many other manufacturers don’t include with their disposals.
Though the 9910 has lower horsepower (1/3 HP) than many of the other Waste King disposals, don’t let that fool you. It has plenty of power for chopping of your food scraps. It seems to be relatively quiet, and many people that are replacing their old Badger disposal claim that it is significantly quieter.

Continuous Feed vs. Batch Feed
There is no performance difference between the batch feed and continuous feed disposals. Continuous feed is the most commonly used type, and is activated by a wall switch. You simply feed food scraps in as you run water down the drain and activate the switch.
In case you’re not familiar with batch feed, you load the disposal with food scraps then use the stopper to activate the disposal. This means the drain is closed before the disposal will activate and nothing else can enter the disposal except water that’s allowed to flow through the stopper. You can see how this would be safer with kids around as no hands can enter the disposal once it has been activated. When you remove the stopper the disposal automatically cuts off.
The Waste King 9910 is a continuous feed, but if you’re looking for a batch feed Waste King puts a “TC” at the end of their name. Check out the Waste King 9930TC for a 3-bolt mount type batch feed.
Is 1/3 HP enough power?
If you’re mostly trying to get rid of softer food scraps, such as soft vegetables and the occasional small meat pieces then you shouldn’t have any trouble with the 9910. Could you grind up an ear of corn or a large piece of steak? I wouldn’t recommend it. The main idea of a garbage disposal, at least for me, is to keep smelly vegetables and meat out of my trash. I currently use, and have for years, a 1/3 HP as of the writing of this review, and it handles everything I throw at it. I cook daily, so is gets used multiple times a day.
Another thing to note, the lower the horsepower the quieter the motor will be. Not always true, but that seems to be the general feedback I see on these garbage disposals.
Note: Here are the official recommendations by Anaheim Manufacturing Company (they make Waste King disposals).
“All types of food waste can be put down your disposer such as vegetable peels, fibrous materials, small bones, fruit pits, etc. Make sure when you do grind materials that you run lots of water through the sink while the unit runs. Items that you SHOULD NOT put down your disposer include large whole bones, clams, oyster shells, whole corn husks, glass, china, plastic, bottle caps, tin, aluminum foil, utensils, caustic drain cleaner, hot grease, or other hot liquids.”
Installation & the 3-Bolt Mount System
First, a little bit about the 3-bolt system compared to the EZ Mount. Waste King says there isn’t any difference between the durability of the two mounting systems, but the 3-bolt system is made of stainless steel whereas the EZ mount is made of aluminum and plastic. There are fewer steps to install the EZ mount system, but don’t let that be the deciding factor since this is an install, if done correctly, will only need to be done once. It isn’t that difficult and if you prefer the stainless steel then don’t let the mounting difficulty sway your decision. Also, the splash guard for the 3-bolt system is not removable, which for most people doesn’t seem to be an issue.
There are a few things to be aware of before you do the install.
- You need Plumber’s Putty. It goes around the sink flange to ensure no leaks occur. Some guides completely miss this step and it is one of the easiest places for a leak to occur.
- You should have a standard 3 pronged outlet in place under your sink.
- If you have a dishwasher, you attach the dishwasher discharge hose to a designated port on the side of the disposal. You must knock out the plug in this port before attaching. DO NOT knock out the plug if you won’t be attaching a dishwasher hose.
The power cord should come already attached to your Waste King disposal. Many other disposals don’t even come with the cord, but this helps ensure you don’t end up with wiring issues that fry your disposal.
The dimensions of the 9910 are 9″ x 9″ x 14.3″. Depending on the piping you have in place you may need to use an extension to get everything to match up correctly.
